1 OVERVIEW
This user manual is aimed to give users a fast introduction to the UNO to PCIe (Ver 1.2) board. This
board is a daughter board for both NuMaker-IoT-M487 (Ver 1.2) board and NK-980IoT. It needs to be
combined with the Quectel EC21 module board, Quectel BG96 module and ZTE ME3630 module
board to connect to LTE. This board can work independently by USB2.0.
Figure 1-1 shows the combination picture of UNO to PCIe board (top) and NuMaker-IoT-M487 board
(bottom). Figure 1-2 shows the combination picture of UNO to PCIe board (top) and NuMaker-IoT-
M487 board (bottom).

Brief Introduction to NuMaker-IoT-M487 Board
The NuMaker-IoT-M487 is a development board using Nuvoton M487JIDAE MCU which includes
Arm®Cortex®-M4 core and rich peripherals. It also has motion sensor and WiFi connectivity on board
as well as plenty of reference materials to let user to quickly develop IoT device applications.
Furthermore, the board provides several interface and connectors for expansion. There are Arduino
Uno compatible interface, mikroBUS™ interface, NuMaker Brick I2C connector, and simulated CMOS
sensor connector.
For more detailed information about the NuMaker-IoT-M487 board, please visit Nuvoton NuMicro
Family ARM®Cortex®-M4 MCUs website to get the related User Manual document.

Brief Introduction to NK-980IoT Board
The NK-980IoT board is a development board based on an ARM®ARM926EJ-S microprocessor
NUC980DK61Y which has very rich peripherals to help users easily to design-in their products or
application systems. The NK-980IoT board uses NUC980DK61Y microprocessor run up to 300 MHz
with built-in 64MB DDR2 memory, 16 KB I-cache, 16 KB D-cache and MMU, 16 KB embedded SRAM
and 16.5 KB IBR (Internal Boot ROM) for system booting from USB, SPI NAND flash and SD/eMMC,
All functions of the NUC980DK61Y are placed on the board, including peripheral interfaces such as
memory (SPI NAND Flash, eMMC, SD), UART, Audio controller(NAU8822L), 10/100 Mb Ethernet
MAC controller, high speed USB(device, HOST), JTAG and EBI, furthermore, the board provides
Arduino Uno compatible interface for expansion. Users can use it to develop and verify applications to
emulate the real behavior.
